Very impressive!
Not sure what you mean here, but maybe this person's experience demonstrates the concept better

I have had two of these things fail on me in the last few weeks. I have mine connected to 5.2 V on the RAW pin. It works fine for awhile, then the Arduino just go bad. Anyone else have this problem????!!!

You’re going to need more than 5.2V for the RAW pin. The RAW pin uses a regulator, which has a dropout voltage of ~1.7V. This means the board is only getting 3.5V, which is not enough. If you have to use the 5.2V supply I would suggest you get the 3.3V version.
Another option would be to regulate to 5V outside of the board and connect to any VCC pin.
I think that its due to small current output 40mA which should be close to 1A as specifications says
the spec means that up to 1A may be safely drawn from it. with only 40 mA it should last much longer. as far as why it would suddenly go to 0v sounds like it may be defective.
